you need the bootable sector from your CD. You can either extract it yourself or download the boot.bin file Save it in a directory other than your Win2K files (such as a temp directory). Second, you MUST use CDRWIN. I tried Nero and Easy CD Creator with no luck. It seems to be the only burner that supports making a CD bootable without emulation. If you don't have it, you can download it . Start it up, and click on the "File Backup and Tools" button. *Note: New versions of Nero and Easy CD will now let you burn bootable CDs without emulation. They may work, but if not please use CDRWIN and these instructions, before you ask for help. *Note #2: Some people, including me, have had problems using CDRWIN 3.8d, I would recommend using 3.8b instead.
Now you will be presented with a screen like this:
Make sure that your settings are EXACTLY the same. The only things you may want to change are:
- For Backup/Test Operation, set it to "Build an ISO9660 Image File" if you want to create an image file. I recommend burning the CD first and if it works, then you can worry about making an image file. Set it to "Build and Record an ISO9660 Image File" only if you are copying the setup files from a CD (perhaps you already slipstreamed SP1 into the Win2K files and made a CD, but now you want it bootable?).
- In the file box, you want to add ONLY the directory that contains the files you copied from your Win2K CD. Don't add each file/directory separately, trust me you'll have problems. Inside this directory should be every file found on the Win2K cd, not just the I386 directory. If you are copying the files from a CD, you want to check the "Preserve Full Pathnames" option (trust me on this, it isn't like dragging and dropping in Nero or Easy CD).
Now, click on the Advanced Options box (it's in the middle). In the Volume Descriptor screen, type in the CD's name in the Volume Label field (in Win2K Pro's case it's W2PFPP_EN, for Win2k Adv Serv it's W2ASEL_EN).
Next, click on the Bootable Disc tab. Enter the exact values listed here, only difference will be the location you saved the boot.bin file to. Make sure you set "Load Sector Count" to 4!!!. That one step gets people every time.
Now click OK, and you're back to the main burning options screen. From here you click the Start button to burn your CD (or make the image file if you chose to do so instead). I also recommend clicking the Save Settings box, so it'll remember these settings for you.
